Domestic Construction of Mandrel Pipe-rolling Mill and Relevant Consideration

The history of domestic construction of the mandrel pipe-rolling mill is reviewed,and domestic situations of seamless steel tube production over the recent years are analyzed. Also presented in the article are relevant consideration about the grim situation concerning construction of the mandrel pipe-rolling mill. The analysis leads to such a conclusion that at present the total production capacity of the advanced mandrel mills in the country is surplus compared with the actual market demand;certain amount of high-end products as rolled by the mandrel mill still depend on import, though in small quantities; the gap between the import price and the export price of seamless steel tubes is getting smaller and smaller year by year;and the tendency towards increase in export is getting slow down. To counter the present situation,it is recommended that seamless steel tube makers in the country make further efforts in development of new product types,and take the differentiation development orientation.
